ExpoDisc PRO 67 mm

ExpoDisc PRO 67mm Digital White Balance Filter The ExpoDisc (patent pending) is a custom white balance filter that allows digital photographers to quickly and easily set an accurate custom white balance. Consistently producing excellent results in natural, artificial, and studio lighting, the versatile ExpoDisc even excels in difficult mixed lighting environments.

The ExpoDisc is far easier to use than any gray card, white card or calibration target. Simply place the ExpoDisc in front of your lens and capture the incident light while setting your camera’s custom white balance. Using an ExpoDisc custom white balance will virtually eliminate the need for RAW or JPEG post-capture color adjustments.

ExpoDisc technology takes a unique approach to setting a custom white balance and producing accurate color. The ExpoDisc essentially uses your camera’s built-in custom white balance capability to turn the camera into an incident color-metering tool. This approach avoids the common problems and inconveniences associated with using gray cards, white cards and calibration targets: unwieldy size, unwanted reflectivity, improper angling and difficulty of filling the frame.
